Reverse Duns number lookup

[DeadManWalks]

Hey now;

Has anyone done a Reverse duns number lookup using any method?

I get duns numbers and want to get what the address is.

Howdy Lazarus,

If all you need is the number, server variables in PHP give a host addr (often a reversed dns addr) as well as an ip addr (usually the standard ip addr). If it's available to PHP running with Apache, there must be ways of getting this in most environments.

What environment are you operating in?

If you're trying to validate a connection source, you could try these folks for an online type service:

Ah. That. Ahem. Of course.

I suppose, then, that it won't help to just hold the numbers up to a mirror?
